VETERINARY TOOTH-CUTTER.

SPECIFICATION forming part of Letters Patent No. 599,586, dated February 22, 1898.

Application filed October 28, 1896. Serial No. 610,802. (No model.) I

shows in perspective a cutter-shield of modified form.

As represented in the present instance, our invention comprises a supporting part (I, having journal-boxes e e, in which is supported the shaft f. On the shaft fis the cutter'h, and connected with the support a is the cutter-shield n, which surrounding the cutter approximately has in one side an opening wherethrough objects are presented to the cutter, and adjacent to the opening it has a guard with guard surfaces in m, against which the tooth or object is allowed to bear during the cutting action. The shield is held in connection with the support a, to permit adjustment laterally, whereby the guard-surfaces m m may be regulated at different dis-' tances from the cutter. To this end the j ournal-box c has its sides grooved or flattened to enter a slot 1) in the shield. It has screwthreaded connection with the support a and carries on its outer end an enlargement or head adapted to engage with a shoulder extending inwardly on the shield. With this construction a suitable turning of the support a, operates to draw inwardly the j ournalboX e, and thereby securely clamp the shield between the end of support a and head end of the journal-box e. An opposite movement of thesupport a operates to release the shield and permits movement thereof laterally on the journal-box e in order to adjust the guard-surfaces m of the shield toward and from the cutter.

The cutter shown has its cutting-surface struck up after the manner of an ordinary file and a degree of coarseness suitable to the work it is intended to perform. It is secured to the shaft by a screw is and may be removed therefrom at will.

In use the support a is made to serve as a handle, which being grasped by the workman is'moved forwardly, carrying the cutter and shield into a horses mouth and against the teeth in position with one of the guarded surfaces no bearing against the outer surface of the teeth and the other against the bot-tom or grinding surface thereof. The corner portions or parts to be removed will then extend inwardly between the guard-surfaces to the cutter. The cutter is rotated rapidly by any suitable mechanism applied to the shaft f, and portions of the teeth desired for removal are thus rapidly cut away, the device being moved from one to another tooth, as desired.

The amount to be removed is regulated by position of the cutter with relation to the guard-surfaces, which may be suitably adjusted to meet the requirements of different operations. The angle at which the cutter is presented to the teeth is determined by the arrangement of the guard-surfaces m m. As shown in Figs. 1 and 2, these surfaces are represented as suitably arranged for operation on teeth along the side of a horses mouth.

In Fig. 3 this cutter-shield is represented with guard-surfaces parallel to the opening and having their lower faces in the same plane with each other and a third surface extending crosswise of the opening. This arrangement is specially adapted for operation on a horses front teeth, in which case the surfaces lateral to the cutter-opening receive the bottom surfaces of the teeth, while the surface running crosswise of the opening extends upwardly against the teeth in front.

We claim 1. A tooth-cutter comprising a handle-like support, a shield on the outer end of the support and having a slot for the admission of a tooth, and a cutter operating within the shield, said shield being provided with a guard-surface adjacent to the exterior of the tooth-receiving slot for regulating the posi tion of the cutter relatively to a tooth; sub stantially as described.

2. A tooth-cutter, comprising a handle-like support, a shield on the outer end of the support and having a slot for the admission of a tooth, a rotary cutter operating within the shield said shield being provided with guardsurfaces alongside the exterior of the slot for regulating the position of the cutter relatively to a tooth; substantially as described.

3. A tooth-cutter, comprising a handle-like support, a shield on the outer end of the handle, and provided with a tooth-receiving slot, and having guard-surfaces along the exterior of the slot, a rotary cutter operating within the shield, and a rotary shaft carried by the handle and to the outer end of which said outter is connected; substantially as described.

4. A tooth-cutter comprising a handle-like support, a laterally-adj ustable shield on the.

outer end of the support, having a tooth-receiving slot and guard-flanges alongside the exterior thereof, and a cutter operating within the said shield, substantially as described.

5. A tooth-cutter comprising a handle-like support, a shield on the outer end thereof having a tooth-receiving slot and provided adjacent to the slot with outwardly-inclined guardsurfaces or work-supporting faces for the purpose set forth, and a cutter operating within the casing; substantially as described.

6. A rotary tooth-cutter, having, in combination, a support, a cutter device, a shield for the cutter device, having a plurality of work-supporting or guard faces arranged at right angles one to another for regulating the position of the cutter device relatively to an object, substantially at described.

7. A rotary tooth-cutter, having, in combination, a support, a cutter device, a shield inclosing the cutter device and having an opening therethrough, and also having faces lateral to the opening, for regulating the position of the cutter device relatively to an object, substantially as described.

8. The combination with the tubular handle provided at its outer end with a laterallyadjnstable longitudinally-slotted shield or casing, of a shaft extending through and rotating in said handle and a cutter on the shaft and operating within the shield, substantially as described.

9. The combination with the tubular handle provided at its outer end with a longitudinally-slotted shield or casing having external guard-flanges at the edges of its slot, and a shaft extending through and rotating in said handle and a cutter on the shaft and operating within the shield, substantially as described.

10. The combination with the tubular handle, provided at its outer end with a laterallyadjustable longitudinally-slotted shield or casing having external guard-flanges at the edges of its slot, and a cutter on the shaft and operating within the shield, substantially as described.

11. The combination of the tubular handle provided at one end with a longitudinallyslotted shield or casing having external guardfianges along the sides and inner end of its slot, with the rotary shaft extending through the handle and provided within the shield or casing with a cutter, substantially as described.

12. The combination with the tubular handle, a casing or shield having a longitudinal and an end slot, and a tubular-headed bearing extending through the end slot into the handle and having a threaded connection therewith whereby said shield may be laterally adjusted, of a shaft extending through the handle into the casing or shield and there provided with a cutter, substantially as described.
